ABSTRACT:
An optical scanning assembly turns an optical element in opposite circumferential directions about a longitudinal axis along which a light beam from a light source is emitted. The optical element and the light source are mounted on individual supports between which torsion elements are connected. An electrical coil arrangement interacts with a permanent magnet to effect the turning movement.
